or convenience 'ofluse, all of the ps Aare preferably made ready for ,foldingby Fig..1.y The top flap 4 is provided witha windowfQ--which is adapted to reveal the' addressed portion of the communication as rittenjonvthe body portion 1, after said top/flap khas been folded "over to close and seal thev communication, as hereinafter deribed.l By the term Window is meant ,either an opening which maybe protected r, not by a transparent panel, or an area Patented June15, 1920.

ap `upwardly'from .the'planeof the paper the iiap which yhas been treated so as to lfrender vit 'sufficiently' transparent for the reading of the address therethrough. In @the present instance the `window 6 is con- '.gst-itutdby an -opening cut in the opaque 'stock of flap 4, and covered by a panel 7 fof transparent or glacine paper, adhesively i secured by'a margin of gum Sover said opening. l, f The window 6 is so located in the-flapv 4 "Pthat'the 'end iapsv 2, 2 when folded in will not interfere therewith, and for purposes portion 1 is provided with an addressield ordesignated space 9. Such address field mayconsist of lines printed. on the paper or a printed rectangle, or other equivalent designation'.

In the use of the blanks, the address is written in the designated space 9, and then the body of the communication is written directly therebeneath, beginning irst on the body portion 1, and extending down as far as need be onto the bottom flap 3.v The latter, due to the location of the address near the top of the body portion 1, may be clear thatthe only restriction on the width of bottom flap 3 is that it shall not, when folded, obscure the address on. the body portion 1. After the communicatie/nf. has been written, the user first preferably folds in the end flaps 2, 2, then folds in the bottom flap 3, and inallyfo'lds in the ,top flap 4; vthe latter carries along its edge/an-adhesive coating 10. for sealing, 'whi its moistened and stuck down vupon the already folded aps, as shown in ig. 2,/ As thus folded,

the address of the communication is revealed through the Window 6, and the sheet is in readiness for transmission through the mails, it being clear that only the address, and no other part of the Communication is revealed until the addressee breaks the seal, or tears off the top flap 4. If desired, the bottom flap 3 may be Jfolded in prior to the folding of the end flaps 2, 2, but the preferred method of use is that first described.

I claim: r.

A mailing sheet having ya rectangular body portion with side flaps and a back flap of such width as to just disclose an address field at the top of'said body portion when l5 said back flap is folded over thereon, and a seal Hap having van opening immediately above its line of fold for registering with the address field on s'aid body portion when folded over thereon, said seal flap then overlapping portons of the side flaps and-of the back flap.
